In February James II moved to Calais and the Jacobite conspirators moved to action. As William drove home to Kensington Palace from his weekly outing in Richmond Park he had to pass along a narrow and muddy lane near Turnham Green. Here he was to be surrounded and murdered. This was the most serious of the several plots against him, but the plotters' security was lax and on 24 February William announced in parliament knowledge both of the plan and of the proposed invasion from France.This act arraigns Sir George Barclay and a number of lesser Jacobites including Johnson alias Harrison, Durant alias Durance, Michael Hare, Major George Holmes, Philip Hanford alias Browne, Richard Richardson, John Maxwell, Bryerly, Plowden and Hungate.Conspirators already languishing in Newgate are named as Counter, [Major ] John Bernardi, Robert Cassells, Robert Meldrum, James Chambers and Robert Blackbourne.
